Taskeng.exe started randomly popping up on the taskbar about a month ago and my laptop was running extremely slow. I downloaded Malwarebytes Anti-Malware and scanned. It quarantined several files, etc. Ever since then I am getting an Installation Error popup for Amazon Cloud upon startup. Multiple programs will not open and will not uninstall. My laptop is still running slow. How can i fix these problems? I don't know where to start.
